AI Technical Summary

Technical Problem

In existing hot runner injection molding technology, conventional water jackets cannot effectively control the gate temperature of highly viscous and sensitive materials such as PET, PCTG, and PVC, resulting in problems such as burns and stringing on the product surface. In addition, 3D printed water jackets are too expensive.

Method used

A composite water jacket structure is designed, including an inner water jacket and an outer water jacket. Inner and outer water cavities are set between the inner and outer water jackets, and heat exchange is carried out through water and oil at different temperatures. The inner water jacket is used for heating, and the outer water jacket is used for cooling. A sealing ring is used to achieve a seal, ensuring that the plastic is in a constant temperature state before it is sprayed from the gate.

Benefits of technology

It effectively improved the cooling effect of the water jacket, reduced production costs, and ensured the quality and appearance requirements of the injection molded products.

Abstract

The utility model discloses a kind of composite water-carrying sleeve structures, comprising: inner water jacket, accommodating cavity suitable for installing hot nozzle is defined in the inner water jacket, pouring gate is opened in the lower end of the accommodating cavity;Outer water jacket, the outer water jacket is set at the outer position of the inner water jacket;Inner water cavity, the inner water cavity is set at the position between the inner side wall of the outer water jacket and the outer side wall of the inner water jacket, and the first water inlet pipe and the first water outlet pipe are communicated with respectively in the inner water cavity;Outer water cavity, the outer water cavity is set on the outer side wall of the outer water jacket, and the second water inlet pipe and the second water outlet pipe are communicated with respectively in the outer water cavity. Its simple structure can effectively improve the problem that water-carrying sleeve cooling effect is not good, and the production cost of water-carrying sleeve can be further reduced simultaneously.
